CUMMINS-6CT-VALVE-GUIDE-INEX-THIN-WALL

3923564 is a thin-wall valve guide for Cummins 6CT engines, suitable for either the inlet or exhaust position. The thin-wall design is specified where cylinder head material has already been machined once and a standard-wall guide would leave insufficient head material around the bore — it's a repair-stage part as much as a maintenance one. Getting guide-to-stem clearance right on installation is what determines oil control and valve life afterward. Orange.net.za dispatches fast, South Africa-wide.
